Reaction Engines Webinar on Corrosion

Webinars 06 September 2022

Reaction Engines Exclusive Webinar: Corrosion – a look at its different forms, impacts and management

Corrosion is omnipresent in our lives and has impacts in engineering sectors ranging from annoying and costly, to design limiting and critically unsafe. A study by NACE in 2013 estimated the global cost of corrosion to be $2.5 trillion USD, which was equivalent to 3.4% of global GDP.

Corrosion is now considered one of many fundamental elements, to be considered in the drive toward “net zero carbon” and “circular economy” initiatives, not least because of the huge amount of resource and materials required to manage and / or replace the damage it can cause.

In the aerospace manufacture, corrosion can threaten the integrity of components and structures alike - thereby compromising safety thresholds which are amongst the highest standards of any sector.

Common types of corrosion which are normally found in structures; surface attack – usually uniform, intergranular corrosion – within the metallography, stress corrosion – often catastrophic at some point, filiform corrosion – typically encountered at interfaces – such as metal surfaces under paint.

TWI is proud of its track record in corrosion science, with skills and equipment that are second to none in addressing corrosion issues for its Industrial Members in all sectors.

Some specifics that will be discussed include;

Galvanic Corrosion:

  • What is it, what does it look like?
  • Susceptible Materials
  • Duration of onset. Accelerating factors
  • How does it impact on mating surfaces of parts?
  • Design and mitigation considerations
  • Metal to Metal structures, and metal to composite structures (use of glass cloth).

Stress Corrosion Cracking:

  • Driving factors, time, load and susceptible materials.

Intergranular Corrosion:

  • Metallic materials and grain structures
  • Identification
  • Testing for susceptibility,

Staining & pitting etc.

There will be a Q&A session after the presentation and TWI is happy to run a more in depth webinar on the above technology, if requested by Reaction Engines staff.


Qing Lu - Principal Project Leader, Metallurgy, Corrosion and Surfacing Technology Group

Qing Lu

Principal Project Leader, Metallurgy, Corrosion and Surfacing Technology Group

Qing Lu graduated with a BSc in Materials Science and Engineering from Harbin University of Science and Technology, China, in 1984. She obtained a Ph.D in Corrosion Science and Engineering at University of Manchester Institute of Science and Technology (UMIST) in Manchester in 1999. This was followed by working on a number of industrial post-doctorate projects at this institute, including corrosion in chemical processing plants and surface engineering studies for automotive applications, between May 2000 and April 2005.

Prior to re-joining TWI in August 2012, she worked for DNV as a senior engineer between November 2011 and August 2012, and for Wood Group Integrity Management as senior materials and corrosion engineer between February 2011 and October 2011 after leaving TWI in February 2011. Prior to joining TWI initially in October 2006, she was appointed as senior research scientist at Westmoreland Mechanical Testing and Research Ltd in UK where her main area of expertise was in failure investigations, primarily related to corrosion.

Her role at TWI carries a particular emphasis in Corrosion Resistant Alloys, which are studied through various types of projects addressing failures, corrosion testing and evaluation, mitigation of corrosion, especially in structures and components joined by welding or other joining techniques.
